CHEM-DDKRAU

A container at a pressure of 1.02 atm contains the following amounts of gases at 25$^o$C: 1 mole of hydrogen, 2 moles of nitrogen, and 3 moles of helium.

If the volume of the container remains constant, and the temperature is raised to 75$^o$C, what will be the final partial pressure of the helium gas (in atm)?
